Biotite Facts -

Biotite is group of common rock-forming minerals found in igneous and metamorphic rocks. It is a name used for a large group of black mica minerals which include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others. The micas vary in chemical composition but have very similar physical properties and are all sheet silicate minerals.

Biotite mica: The mineral Biotite information and pictures

Biotite is a very common form of mica. It is named in honor Jean Baptiste Biot (1774 - 1862), a French physicist, mathematician, and astronomer who researched the mica minerals for their optical properties. Because of Biotite's abundance, its presence is usually lacking in collections except for it being an accessory mineral to other minerals.
